BMW unveiled the No.25 concept car to celebrate the race car which won several racing titles nearly 40 years ago. BMW Chief Designer Karim Habib says that the new concept was always intended to be unveiled with the BMW Motorsport racing livery and despite being a fully functional prototype, the concept will just remain a design study.

Compared to the first CSL concept unveiled in May, the new version is also an improved one. BMW has made several changes to its exterior design, starting with the front grille which now features a mesh found on race cars while forgoing the traditional slats in the kidney grille. Next, the front splitter has also been modified to provide additional downforce as you would need in a track car.

The side gills on the side have also taken a different design, gone are the three-metal pieces found on the first design study. BMW design team also revamped the three-pierce wheels to deliver a cleaner look.

Inside, BMW took a minimalist approach with most of the information being projected onto the high-tech helmet developed in collaboration with PUMA. The cabin features the wood trim seen on the original 3.0 CSL, along with fixed racing seats and a carbon fiber roll cage. A fire extinguisher can be activated in case of emergency with the push of a button.
